Fieldeng
Get on Android

The phone is the instrument.

Measure. Calculate. Diagnose. Record.

Fieldeng is an offline toolbox for engineers and technicians. Capture a reading at a site, run the calculation, read the formula, keep the record. No account. No cloud for core use.

Get on Android

$9.99 one-time when the Play listing ships. Camera and ML captures come next; these shots are the live app on a Pixel 8.

Capture at the site, then file it.

Type it, speak it, or photograph a display. You confirm every camera reading before it fills a field. Home keeps the last work. Sites hold the place. A number without a place is a notepad.

Fieldeng Home: Read instrument, recent Wi-Fi readings filed on this device. Fieldeng Home in dark theme: nearby map and recent readings.

Every tool has the formula on the face.

Calculators are part of the kit, not a mystery box. Simple is the working face. Reference shows the expression, the assumptions, and where it came from. Learn the job while you run the number. ML never computes the engineering result.

life = (m × C × u × 3600) / I

Anode Life, from the Reference tab. Same pattern on the rest of the catalog.

Anode Life Reference tab with formula, assumptions, and provenance. Anode Life Reference tab in dark theme, same formula and assumptions.

The loop the app is built around.

Measure

Field capture: number, note, voice, or camera. Phone instruments for level and bearing. Confirm before it is saved.

Calculate

Domain tools from electrical and CP through HVAC, fluids, and survey. Simple on the surface, Advanced when the job needs it.

Diagnose

Field context on the result. Observations, never a pass or fail, never a substitute for qualified judgment.

Record

Save to a site on this device. Compare later. Export when you choose. Core use works with no signal.

One kit, many jobs.

Open a module. Every name is a calculator on the phone, with the formula on the Reference tab.
